Trial summary

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of selenium may keep bladder cancer from growing or coming back. It is not yet known whether selenium is more effective than a placebo in preventing cancer recurrence in patients with bladder cancer. Read more about this study

About this study

Official title: Phase III Randomized Chemoprevention Study of Selenium on the Recurrence of Non-invasive Bladder Cancer

RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of selenium may keep bladder cancer from growing or coming back. It is not yet known whether selenium is more effective than a placebo in preventing cancer recurrence in patients with bladder cancer.

PURPOSE: This randomized phase III trial is studying selenium to see how well it works compared with a placebo in preventing cancer recurrence in patients with bladder cancer.

Read the detailed description

OBJECTIVES:

Primary

  • To determine the effect of selenium, when administered with standard care, in preventing the recurrence of bladder cancer in patients with non-muscle-invasive transitional cell carcinoma of the bladder at risk for recurrence.

Secondary

  • To determine the effect of selenium on the recurrence of bladder cancer, in terms of histological type, number, and size.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive oral placebo daily in addition to standard care.
  • Arm II: Patients receive oral selenium daily in addition to standard care.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing selenium in people with Bladder Cancer, run by KU Leuven at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of selenium in preventing the recurrence of bladder cancer (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00729287, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 May 2016.
